Prussian-blue nanoparticles and PNIPAM nanohydrogel gates form an abamectin platform responding to alkaline conditions, temperature and near-infrared light.
Under the reported test conditions, alkaline-triggered release reached 91.1% in 24 hours and diamondback-moth insecticidal activity reached 81.7%.
The work evaluates UV protection, leaf adhesion and switching between release modes. These results are not universal field-performance guarantees.
